According to the first paragraph,
Laws of transformation are needed so that a theory which describes a phenomenon w.r.t. one reference frame could be applied to explain the same phenomenon w.r.t. another reference frame.
Does it mean that Laws of transformations are different for different theories?A physical statement of what these invariants are is called a principle of relativity.
For Galilean transformation, acceleration is invariant.
So, does it mean that the following statement:
"Acceleration is invariant under Galilean transformation ."
is a principle of relativity for Newtonian dynamics.
So, for different theories , there will be different principle of relativities. Right?
Fundamental equations of theory usually defines the principle of relativity applicable to the theory.
e.g.
The equation F = ma defines the principle of relativity, i.e. force in Newtonian Dynamics.
